You can invest in a SPAC by purchasing its shares, units, or warrants through a standard brokerage account, just like buying any other publicly traded stock. SPACs, or special purpose acquisition companies, are shell companies that raise money through an IPO with a single goal: find a private company to merge with and take it public. Your investment experience and risk profile change dramatically depending on when you buy and what you buy, so understanding the SPAC lifecycle is essential before putting money in.
How a SPAC Works
A SPAC starts as a blank-check company. A management team, called the sponsor, forms the SPAC and takes it public through an IPO. The money raised from that IPO goes into a trust account, where it sits earning interest until the sponsor identifies a private company to merge with. The SPAC typically has 18 to 24 months to find a target and complete a deal.
Once a target company is identified and a merger is announced, the SPAC’s public shareholders vote on whether to approve the transaction. They also get to decide separately whether to redeem their shares (get their money back from the trust) or stay invested and become shareholders of the newly combined public company. If the merger closes successfully, the target company becomes a publicly traded entity, and the SPAC’s ticker symbol usually changes to reflect the new company’s name and brand.
If the SPAC fails to complete a merger within its deadline, the trust is liquidated and shareholders receive their pro-rata share of the money held in it.
Units, Shares, and Warrants
When a SPAC first goes public, it typically sells “units.” Each unit usually consists of one share of common stock plus a fraction of a warrant. A warrant gives you the right to buy additional shares at a fixed price (often $11.50 per share) at some point in the future. After a set period, usually 52 days after the IPO, the units can be separated, and the common shares and warrants begin trading independently under their own ticker symbols.
This means you have three ways to get exposure to a SPAC through your brokerage account:
- Units: The bundled package of a share plus a warrant fraction. These trade under a ticker that typically ends in “.U” or “U.”
- Common shares: Straight equity in the SPAC, traded under the base ticker. These are what you redeem if you want your trust money back before a merger closes.
- Warrants: These trade separately, usually under a ticker ending in “.WS” or “W.” Warrants are more speculative because they become worthless if no merger happens or if the stock price never rises above the exercise price.
Each carries a different risk profile. Common shares near the $10 IPO price have a built-in floor because you can redeem them for roughly that amount from the trust. Warrants have no such floor and can lose all their value.
Buying Before vs. After a Merger
The timing of your purchase shapes your entire risk and return picture.
Pre-Merger (Searching Phase)
When a SPAC is still looking for a target, its common shares typically trade near the $10 IPO price. Your downside is limited because the trust account backs each share at roughly that level, and you can redeem if you don’t like the eventual deal. The tradeoff is that your money is essentially parked. You’re earning trust interest returns while waiting, but there’s no operating business generating growth. Many investors buy SPACs during this phase specifically for the downside protection, treating it almost like a cash-equivalent position with option-like upside if a popular deal is announced.
Post-Announcement, Pre-Close
Once a SPAC announces a merger target, the share price often moves based on market enthusiasm for the deal. Shares can spike well above $10 or fall below it. You still have redemption rights during this window (the SPAC must provide disclosure documents outlining the process), but the market price and the redemption value may diverge. If shares are trading at $14 and you believe in the target, holding through the merger could pay off. If the deal falls apart, the shares typically drop back toward trust value.
Post-Merger
After the merger closes, the combined company trades as a normal public stock. The trust account safety net is gone. You’re now evaluating the company on its fundamentals, revenue, management team, and competitive position, just like any other stock. Historically, many SPACs have underperformed broader market indexes after completing their mergers, so post-merger investing requires the same due diligence you’d apply to any individual stock pick.
How to Exercise Redemption Rights
One of the most important protections for SPAC investors is the right to redeem your common shares for your pro-rata portion of the trust account. This means if you bought shares at $10 and the trust has grown slightly from interest, you might get back $10.30 or so per share, regardless of where the stock is trading.
To redeem, you follow the steps outlined in the proxy statement or tender offer documents that the SPAC sends before the merger vote. The process typically involves tendering your shares through your broker before a specified deadline. If you miss the deadline, you lose the right to redeem for that transaction and become a shareholder of the post-merger company. Pay close attention to the dates in those filings.
Note that warrants do not carry redemption rights. Only common shares can be redeemed for trust value.
What to Research Before Buying
SEC rules that took effect in July 2024 strengthened disclosure requirements for SPACs. Sponsors must now provide clearer information about their compensation, conflicts of interest, and the dilution that existing shareholders face. They also must disclose whether the SPAC’s board determined that the merger is in the best interests of shareholders. When projections are used to market a deal, additional disclosure about those projections is required, and the safe harbor protections that normally shield companies from liability for forward-looking statements are narrower for SPAC transactions.
Before investing, review these key factors:
- Sponsor track record: Has the management team successfully completed SPAC mergers before? What happened to those companies after the deal closed?
- Sponsor compensation and dilution: Sponsors typically receive a “promote,” often 20% of the post-IPO shares, for a nominal investment. This dilutes your ownership significantly. Check the SEC filings for the exact terms.
- Trust value per share: This is your effective floor price for redemption. You can find it in the SPAC’s quarterly filings.
- Time remaining: A SPAC nearing the end of its merger deadline without a target may liquidate, returning trust money but potentially leaving warrant holders with nothing.
- Target company fundamentals: Once a deal is announced, evaluate the target like any other investment. Revenue, growth trajectory, competitive position, and valuation relative to public peers all matter.
Where to Find and Buy SPACs
SPACs trade on major exchanges like the NYSE and Nasdaq. You can buy them through any brokerage that offers stock trading. To find active SPACs, search financial data sites that track SPAC listings, which show the current phase (searching, announced deal, or approaching deadline), trust value per share, and merger targets.
When placing an order, make sure you’re buying the right security. Double-check whether you’re purchasing common shares, units, or warrants by confirming the ticker symbol. The difference matters enormously for your risk exposure and redemption rights.
Tax Considerations
SPAC investments are taxed like other stock investments. If you hold shares for more than a year before selling, gains qualify for long-term capital gains rates. If you redeem shares for trust value, the difference between your purchase price and the redemption amount is a taxable gain or deductible loss. Warrants that expire worthless can be claimed as a capital loss. When a SPAC merger closes and your shares convert into shares of the new company, that exchange is generally structured as a tax-free reorganization, meaning you don’t owe taxes until you eventually sell.
The Dilution Factor
Dilution is the single most misunderstood aspect of SPAC investing. The sponsor’s promote, additional shares issued to the target company’s owners, and any private placement shares sold alongside the merger all increase the total share count. By the time a merger closes, the shares you bought in the IPO may represent a significantly smaller slice of the combined company than you expected. If 70% of public shareholders redeem their shares before a merger, the dilution effect on remaining holders becomes even more pronounced.
Read the merger proxy carefully to understand how many total shares will be outstanding after the deal closes and what percentage your investment represents. This is often the difference between a SPAC that looks cheap on paper and one that’s actually overvalued relative to its target company’s fundamentals.
